Thermoset elastomers, which are also rubbers in the traditional sense, thermoplastic elastomers, abbreviated to TPEs, have been increasingly used commercially in the last 90 th century. This classification also illustrates two different ways in which these two types of elastomers are processed: the rubber is processed by thermosetting equipment, and the TPE is processed by thermoplastic equipment.
Fluoroelastomers were initially used in the aerospace industry as high-performance elastomeric sealing materials, after which the field of application of fluoroelastomers has gradually expanded to many other industrial fields, in particular the automotive industry, the hydraulic drive and the chemical industry.
